Quirrell.
It's not just about him not bothering to check whether he had a visa to Fuyuki city.
It's about him always having claimed to be a Slytherin.
Despite actually being... a Ravenclaw?
That doesn't sound like the kind of claim you could get away with it, and Quirrell should know that, but he still makes it, and... gets away with it?
Doesn't any current Hogwarts student have parents/relatives/family friends who knew Quirrell from his time back at school?
And it's blindingly, blitheringly obvious by this point that Quirrell is H&C. Too obvious.
Why would Quirrell orchestrate this in a way that ends in him being interrogated by the DMLE? Compare with his attempted Dementation of Harry.
In fact, the same thing would apply even if he weren't H&C. I'd expect him to have come up with a better way of handling it. One with more plausible deniability.
Conclusion: Quirrell planned to be interrogated by the DMLE. Quirrell planned to have his cover blown. Why? I haven't the slightest idea.
I still don't know what to make of the Ravenclaw thing, though.
Edit: Just checked to see if Quirrell had actually claimed to be in Slytherin instead of just implying it. Yes, he had.
Yes, I was in Slytherin and I am offering to formulate a cunning plot on your behalf, if that is what it takes to accomplish your desire.
Edit: Of course he planned to be interrogated; he couldn't afford to be inside Hogwarts when Dumbledore began searching for Tom Riddle.
I still don't know why he'd want to blow his cover, though.
The line about having been sorted into Ravenclaw could be as fake as the Fuyuki City thing, Scrimgeour's play. Quirrell's apparent failure could just be a way of getting temporarily detained, while Dumbedore's looking for Riddle and Harry wants his help. His cover could actually be pretty solid, so he'd just shrug off Scrimgeour's suspicions once it's time to go.
